There was a long discussion on neutering here:

Most of the studies on the bad effects of neutering involve large-breed dogs, and may not be applicable to Yorkies. The consensus we reached by the end of the long, long thread is that for female Yorkies, it's best to have them spayed after their growth plates have closed, but before their first heat, around 8 months of age. (X-rays can be taken to determine if the growth plates have closed.)
UC Davis will be releasing the results of a new study on the effects of spay/neutering of 30 breeds of dogs on June 26. I do not know if Yorkies are included, but I'll give an update if I can find the information.
